10.6.1 The Header

The first two lines at the top of the E2 screen are

referred to as the screen header. This area of the screen contains the time and date, controller name, subnet and node number, and alarm and failure notifications. In addi- tion, it contains highlighted indicators and icons to show when a user is operating in a particular mode, such as full options, edit, macro record, or insert mode.

If the E2’s Global Data feature is being used to supply outside air temperature and outside relative humidity val- ues, these values will also be displayed in the header.

At the very top of every screen in the E2, there are icons that indicate various stages of activity, number of users logged into the controller, battery alerts, connectivity status, and more.

10.6.2 The Function Keys

Figure 10-7- Home Screen Function Keys (RX version shown)

At the very bottom of every screen in the E2, there are five boxes labeled  through . These boxes are the function key descriptions. The function key descrip- tions show what each of the five function keys do when pressed. (Options will vary depending on the type of con- troller being used.)

Function key usage often varies depending on which screen or field E2 is currently in.

10.6.3 The Help Line

The line directly above the function button menu is called the help line. The help line displays information about the currently selected field, such as general descrip- tions, possible ranges, and other information to help a user maneuver around and/or configure the field.

and press . Use the arrow buttons to move

around the screen and notice how the help line changes as the cursor moves from the setpoint to status sections. When finished, press the  key to return to the Home screen.
